“…Study of hypoeutectic Al-Si [37] cast by spray technique with Si content percentage 6.91 and 10.1 at 0.75 m s −1 sliding speed under fixed load of 3 kg revealed that the wear resistance depends upon the shape and size of Si particles and alloy having 10.1% Si have lower rate than alloy having 6.91% Si, as Si is hard substance and with increase in silicon percentage hardness increases, so wear rate decreases. Mittal et al [54] used pin on disk machine to study the wear of spray casted Al-Si-Pb alloy. Study of wear profile shows decrease in wear rate as we traverse from center to periphery of the alloy sample.…”

This article addresses the tribological characteristics and the influence of mechanical work on the porosity of spray formed Al–Si–Pb alloys. Al‐alloys are extensively utilized in industry due to their self‐lubricant qualities, particularly in the bearing company. In the case of immiscible alloys, the spray approach is the most convenient way to adopt since it allows for single‐step fabrication. The spray process has a high cooling rate, which affects the microstructure of alloys and results in equiaxed grain morphology. Spray deposition and several factors affecting to it are discussed here. This study examines the effect of secondary processes such as cold rolling, hot rolling, extrusion, and so on on porosity, hardness, tensile strength, and tribological behavior. A comprehensive knowledge of the principles of spray techniques and their respective influence on tribological properties are discussed in this perspective by comparing the available literatures, and a future scope for better development is emphasized.

“…Antifriction aluminum alloys have been developed for replacement of antifriction bronzes in journal bearings [4]. Basically, developments of antifriction aluminum alloys aim at increasing the lead and tin contents in the alloys [9][10][11][12]. However, mechanical properties of the alloys could be worsened in that case [13].…”

The paper investigates the relationship between the tribological properties/compositions of new aluminum antifriction alloys and compositions of the secondary structures formed on their friction surfaces. Eight alloys with various compositions have been analyzed. The elemental compositions of the secondary structures on their friction surfaces have been determined. The relationship between the alloy secondary structure compositions with wear rate has been found. An attempt has been made to determine the secondary structure composition patterns based on the non-equilibrium thermodynamics and self-organization theory.

Wear behavior of spray formed Al-17Si and Al-17Si-10Sn alloys was investigated using a pin on disk type wear testing machine and characterization of this Al-Si and Al-Si-Sn metal matrix composite alloys is done using optical microscope. The alloys were spray formed in an environmental chamber using nitrogen gas and a deposition distance of 380mm. The spray formed alloys showed considerable microstructural refinement with uniform distribution of Si particles in Al-Si alloys and that of Sn and Si particles in the matrix of primary Al phase of Al-Si-Sn alloys. Dry sliding wear behavior of these metal matrix composite alloys was studied as a function of sliding distance, applied load and sliding velocity. The wear response parameters such as wear rate and frictional force were measured. A considerable increase in the wear resistance of the alloy is observed with addition of Tin(Sn). The improved wear properties and characterization of the alloy containing Sn are discussed in light of the microstructural features of spray formed alloy.
